Description

用于包装食品的容器
技术领域
本发明涉及一种用于包装食品的容器，其具有容器壳体、基座和顶部，其中至少顶部由塑料材料制成，在顶部具有可再封闭的卸料孔。
背景技术
在实际应用中，这种容器是已公知的，其中大部分由一块塑料材料制成，在使用中，或者从容器的卸料孔中向外排出食品内装物时，不能完全令人满意。
例如，美国专利US-4213537公开了一种用于一次性纸容器的塑料盖，其中卸料孔的盖子不能实现再封闭。
美国专利US-5743427公开了一种具有卸料孔的容器盖，以便食用容器中的饮料，但是，其中卸料孔的区域结构仅仅是为食品内装物向外流出设计的。
美国专利US-4298146、US-4310105和US-4334639公开了一种用于容器盖子的封闭物，当盖子处于开启状态时，封闭物与盖子分开。
但是，上述现有技术的文件中没有一篇公开具有可再封闭卸料孔的顶部的容器，以便于容易分配非液体食品。
发明内容
本发明试图解决上述问题，分开制作具有上述类型的顶部和容器壳体，再将顶部安装到容器壳体上，提供这种容器，与此同时，提供一种有效的，而且消费者可以接受的分配容器中食品内装物的结构，特别是所述内装物是非液体食品。
本发明的目的是寻求提供一种具有基本上呈凸出形状的顶部的容器，其具有容器壳体，由此，分开制造容器壳体和容器的顶部，然后将它们两者各自连接，并且在顶部具有卸料孔，盖子基本上呈凹陷形状。
因此，按照本发明提供一种容器，其中具有容器壳体，所述壳体具有基座和顶部，而且，至少顶部由塑料材料制成，还具有可再密封的卸料孔，顶部具有较低的周边缘，所述周边缘使顶部与容器壳体相互连接，卸料孔由盖子覆盖，所述盖子通过薄膜铰链连接到顶部上，所述薄膜铰链所在的位置靠近顶部的最高点，其特征是：顶部基本上呈凸出形状，盖子基本上呈凹陷形状，当盖子，处于开启状态时，盖子位于和顶部相靠的位置，在此状态下，盖子与顶部具有比较大的相互吻合的表面。
容器壳体形成容器内腔体的侧壁，容器具有顶部和基座，由顶部和基座分别形成容器内腔体的顶部和底部。
基本上呈凸出形状意味着具有各种凸出形状和轮廓特征，但是，其中凸出形状侧面部分的角度大于整个凸出形状的角度。
基本上呈凹陷形状意味着具有各种凹陷形状和轮廓特征，但是其中凹陷形状侧面部分的角度大于整个凹陷形状的角度。
这种容器用于包装食品，特别是用于包装冷冻食品，例如冷冻冰块，或者冷冻糖果，或者类似物。但是，任何希望从可再封闭容器中便于分配的食品，都可以采用这种容器来包装。
采用盖子覆盖卸料孔，所述盖子通过薄膜铰链连接到顶部。盖子借助薄膜铰链能够连接到顶部，以便容易开启或封闭卸料孔。薄膜铰链位于顶点度最高位置的附近，当盖子处于完全开启状态时，盖子位于和顶部相靠的位置。
所谓“最高位置”是指顶部的部分，这一部分远离容器的基座，一般沿着垂直方向延伸，这一部分高于顶部的其它部分。
盖子基本上呈凹陷形状，当盖子处于完全开启状态，并且与顶部相靠时，盖子的大部分与顶部的凸出表面相互吻合。
最好，容器壳体基本上由扁平的板坯卷曲成型，特别是采用纸板板坯。在本发明的特殊方面，容器具有塑料材料的顶部，和由纸板、纸或其他类似的、不同于塑料的材料制成的容器壳体。
本发明的另一个方面是通过由薄膜铰链断开的圆周部分将盖子模制到顶部，其优点是，为盖子提供卫生和具有开启显示装置的密封件。
本发明的另一个优点是容器壳体呈喇叭形开口结构，或者是向下方扩展的结构，即呈锥形结构，以便使容器与顶部连接的周边小于容器与底座连接的周边。
本发明还有进一步的优点，其中基座基本上呈扁平形状，或平直形状，基座的边缘连接容器壳体的下边缘。这种结构的优点是加强了容器的稳定性。
本发明的另一个优点是，按照本发明的另一个方面，基座具有向内拉伸的内板部分。这进一步改善了容器的稳定性，而且提高了容器的搬运稳定性。
本发明的另一个优点是，基座面向容器内腔体的一侧可以设置密封件。因此能够简单地使基座合适密封到容器壳体的边缘。
按照本发明的另一个方面，最好，基座被制成一个深度拉伸的盘状元件，其内侧能够设置一个密封件，特别是由聚乙烯覆盖物构成的密封件。这种结构允许容器包装各种水基产品，容器不会受内装物，例如冷冻的水基产品的影响。
本发明的另一个方面的优点是在盖子上设有拉片，或者类似物，拉片模制在盖子上，在顶部设有与拉片相应的连接件，以便当盖子位于开启状态，并且与顶部相靠时，该连接件与拉片形成扣接连接。
本发明的优点是能够有效地保持盖子离开卸料孔，以便有效和容易排出容器中的内装物。
根据放置在容器中的食品类型，以及被包装在容器中的内装物尺寸，确定容器的尺寸。最好容器具有足够大的尺寸，以便容纳一种食品，例如冷冻糖果，或冰块。
附图说明
下面参照附图进一步描述本发明。
图1是表示容器的立体图，其中描绘了本发明的壳体，和位于壳体相对端部的顶部和基座。
图2是与容器壳体相邻的顶部的水平投影图。
图3是容器的纵向剖视图。
图4是放大的局部剖视图，其表示顶部边缘和与其相配合的容器壳体的边缘。
图5是图5所示两个部件处于组装状态的剖视图。
图6是类似于图2的水平投影图，但是图2中封闭的盖子被打开。
图7是容器的纵向剖视图，其中表示了图6所示的开启的盖子。
具体实施方式
附图中描绘的容器2装有容器壳体1，所述容器壳体1具有较低的圆形边缘线26，其中容器壳体由扁平的纸板板坯卷曲形成，并且具有纵向密封区域5。容器壳体也可以由塑料材料制成，由此可以通过卷曲一块塑料薄膜，通过拉伸成型。由塑料材料制成的顶部3位于容器的上表面，而基座4位于容器的下侧。在附图所示的实施例中，在填充容器之后，再安装基座，所述基座4呈扁平状态，以致容器可以放置在平滑表面6上。在容器壳体1的下端具有卷曲的边缘7，所述基座4固定在卷曲的边缘7上。具有多种方式可以形成上述结构。在附图中，在基座边缘具有卷曲的凸缘8，在壳体1下端卷曲的边缘7和基座4中卷曲的凸缘8相互固定在一起。但是，基座4的边缘也可以呈平面形状，并且密封在壳体1下端面卷曲的边缘7的下侧。此外，基座4的中央部分可以被向内拉伸形成内板部分，由此可以采用塑料材料或纸板制造基座4。当基座由纸板制成时，通常在基座的内表面覆盖可密封的塑料薄膜层，聚乙烯是特别合适的材料。当形成这种结构时，在容器中的内装物向基座表内施加正压力，有助于塑料薄膜与纸板之间的密封。
容器壳体1的上边缘9向内折叠，形成双边缘10，所述边缘10的内折板18朝向容器2的腔体内侧伸出。顶部3具有圆形凹槽12，所述凹槽12向下侧开启，双边缘10可以被推入凹槽12中。环形凸缘13在凹槽12中延伸，以便稳定地夹持双边缘10。在使用，这种结构形成满意的连接，但是，当容器被完全排空时，这种连接结构很容易被分开，以便对构成容器的材料分别进行处理。也可以采用具有单一厚度的材料代替双边缘10，这仅仅取决于制造容器壳体1的材料厚度。
顶部3具有卸料孔23，所述卸料孔23由盖子24密封。所述盖子24通过薄膜铰链25连接到顶部3上，并且，在原始状态，盖子24的整个周边围顶部穿孔连接到顶部3上。当在顶部施加压力，第一次打开盖子24时，使盖子与顶部3的连接部分(穿孔部分)分开，盖子24可以围绕薄膜铰链25向外摆动。顶部3具有整体凸出形状，与此同时，盖子24具有向内凹陷的圆弧部分。当然完全打开盖子24时，盖子24可以与顶部3的外表面相靠。因此，可以完全打开卸料孔23。还可以设置附加的扣接连接件28，其可以将盖子24相对于顶部3夹持在开启位置。拉片27与扣接连接件28相互扣接配合，所述拉片27被模制在盖子24上，拉片27的设置位置与薄膜就连25相对置，以便容易拉开盖子24。
本专业的普通技术人员在本发明容器的范围内，还可以获得其他经过修改的方式。
